RFC functionsmoduls - Parameters behind the sap-gateway

hello expert,

we are useing SAP RFC functionsmoduls, which are called over a BIZZ talk server. So far OK.

But sometimes a certain parameter comes cryptic into the functional module and i do not know why. I would like to examine the incoming parameter now directly behind the SAP-Gateway. Does a tracing/logging are exist for this?

thanks in advance

Ralf
